I have a 14" ibook (1.4ghz late model) and the backlight on the display will not stay on. The computer is working fine (except for this) and the display works (you can see it faintly when shining a bright light on it) but the backlight is not on. The brightness settings are all the way up so that's not the problem. I also reset the pram which did nothing.. So then I tried resetting the nvram and restarted the computer. This actually worked and the backlight was on, everything running smooth for about 2 hours.. then the backlight randomly shut off again. I tried resetting the pram/nvram like I did before but this time it did nothing and I cannot get the backlight to come on at all now.. It used to come on when I opened firmware setting but now it doesn't even do that.. Does this sound like a video card problem? Any other suggestions to try and fix this? I don't know if this has anything to do with it but recently the computer also started making clicking noises for about 3 seconds when waking up from a sleep. sounds like it's coming from the optical drive so it's probably nothing..
